| Question | Answer |
|---|---|
| What would happen if Earth had no tilt of its axis? | There would be no seasons. |
| The Sun-Earth-moon positioning in space can cause (3 answers) | Seasons, eclipses, and phases of the moon |
| Earth has _______ because the Earth's axis is tilted at 23.5*. | Seasons |
| If the season is winter in the northern hemisphere, the season will be ____ in the southern hemisphere. | Summer |
| Approximately how many days are needed for Earth to complete one full revolution around the Sun? | 365 |
| Seasons are caused by a combination of …. Name all three. | Tilt of the earth’s axis, the curvature of earth’s surface, the angle sunlight strikes earth’s surface |
| When the moon and the sun are in line with one another, what effect does this have on the Earth's tides? | The gravity of both the sun and the moon pull on the water to create even higher tides. |
| How many tides are experienced in one rotation of earth? | There are two high tides and two low tides. So the total is 4. |

| When Northern Hemisphere (US) is tilted TOWARDS the sun (more direct sunlight), what season is it? | Summer Solstice |
| When Northern Hemisphere (US) ISN'T tilted towards nor away from the sun (equal light-northern/southern hemisphere), what season could it be? | Equinox (Autumnal/Fall or Vernal/Spring) |
| When Northern Hemisphere (US) is tilted AWAY from Sun (indirect light), what season is it? | Winter Solstice |
| True or False: We (northern hemisphere) are closer to the Sun in Summer. | False (actually closer in the winter due to elliptical orbit) |
| True or False: The tilt of Earth is always the same, tilted 23.5 degrees towards North Star (Polaris) | True, the tilt doesn't flip flop back and forth |
| When the moon perfectly aligns in between the Sun and Earth it causes a........... eclipse? | Solar Eclipse |
